From jocelyn at ausnog.net Wed Apr 2 18:37:54 2025 From: jocelyn at ausnog.net (Jocelyn Bateman) Date: Wed, 2 Apr 2025 17:37:54 +1000 Subject: [AusNOG] AusNOG 2025 - Call For Papers is Open! Message-ID: Hi AusNOG, The Program Committee is very happy to announce that the AusNOG 2025 Call For Papers is now open! We are looking for presentations that an audience working predominantly in the network operating space will find interesting and useful. As always, we do not accept marketing or sales material as part of any presentation. The CFP will close on May 30th 2025. This allows time for the Program Committee to review papers and choose the program. Please express your interest and submit a short abstract of the topic you'd like to present, via our portal; https://cfp.ausnog.net/ausnog-2025/ Thank you, and see you in Melbourne, for AusNOG 2025! Event dates and details here; https://www.ausnog.net/ Kind Regards, Jocelyn Bateman, Program Chair Australian Network Operators Group (AusNOG) https://www.ausnog.net/ From chris at datachaos.com.au Thu Apr 3 19:13:24 2025 From: chris at datachaos.com.au (Chris Lee) Date: Thu, 3 Apr 2025 18:13:24 +1000 Subject: [AusNOG] Telstra TIPT SIP 5060 problem Message-ID: Hi all, We have a few SIP devices that we had configured to use TIPT over Internet and had been working fine for some years now on Port 5060. Since around 14th March I noticed that our monitoring to Port 5060 of the Telstra TIPT SBC stopped working. Have now discovered that those same SIP devices can no longer register with TIPT, and can see on the graphs of the network ports for those devices the traffic seems to have dropped off the cliff around 14th March. So I've tried to email TIPTFaults at team.telstra.com email which was helpful in the past, but now gives me an autoreply for how to raise an incident in Telstra Connect. Great, so I go to Telstra Connect, and just so happens I do have an account and login successfully. And there's absolutely no option under my login to raise an incident. The help & support page is blank. Try to use the Feedback link in there and get "Error ! An error occurred while trying to send your feedback". Switched off our proxy to be sure, and same issue. Anyone know if this is the case that SIP Port 5060 support on TIPT over Internet is now dropped, and if so what's the correct encryption settings for SIP Port 5061 ? Or are third party SIP devices just no longer allowed on TIPT? Thanks -------------- next part -------------- An HTML attachment was scrubbed...

This seems a bit of a pain for me - whilst I wouldn't normally run over the 24 amps there have been times i have had to run over - but under 30 for days if not a couple of weeks. Currently I'm trying to order into japan (omg), lot of their stuff is imported which means it comes with the USA specs. so 24/30 amp setup.. Interestingly also noted that when you read the fine prints its actually 2 x 20amp breakers - 1 breaker per bank ..

Real-world usable power also depends on: The power factor (PF) of the connected equipment. Whether the PDU is installed in a hot aisle or cold aisle. If the load is continuous, you must also apply the 80% continuous load rule as per AS/NZS 3000. Example ? 30A Circuit @ 230V Cold Aisle Scenario (23?C, PF = 0.9): No temperature derating needed at 23?C. Apply 80% derating for continuous load: 30A ? 0.8 = 24A usable Real usable power: 24A ? 230V ? 0.9 = 4968 W Usable continuous load = ~4968W Peak load capacity (non-continuous): 30A ? 230V ? 0.9 = 6210 W (for short-term bursts only) Hot Aisle Scenario (40?C, PF = 0.8): Apply both continuous and thermal derating: 30A ? 0.8 (continuous) ? 0.87 (thermal) = 20.88A Real usable power: 20.88A ? 230V ? 0.8 = 3848 W Usable continuous load = ~3848W Cold Aisle (23?C) 24A 0.9 4968 W Hot Aisle (40?C) 20.88A 0.8 3848 W On Tue, Apr 8, 2025 at 2:48?PM Alex Samad wrote: > Hi > > I'm having the pleasure of looking at PDU's and trying to standardise over > US / UK / Japan / Aus > > Something I didn't know was the standard in the US for derating electrical > devices. whilst I normally plan for max normal draw of around 80% of > rating. seems like PDU for USA have a derating value. > > So I am seeing 30amp @ 230v in and line rating of 24amp and max 30amp. > The notes seems to suggest you can go over 24 amps but only for a very > short period of time - seems like minutes. > > This seems a bit of a pain for me - whilst I wouldn't normally run over > the 24 amps there have been times i have had to run over - but under 30 for > days if not a couple of weeks. > > Currently I'm trying to order into japan (omg), lot of their stuff is > imported which means it comes with the USA specs. so 24/30 amp setup.. > Interestingly also noted that when you read the fine prints its actually 2 > x 20amp breakers - 1 breaker per bank ..

But from an electrical engineering perspective conductor heating (what you're managing by derating) is a larger issue in 100/110V countries as I^2R losses are greater. Higher voltage (lower current) means the resistance of the conductors causes less heating thus you're less likely to go outside of the conditions for which the conductors (and moreover their insulation) are rated.

In one case we had sparkies in a cherry picker connecting fibre to hundreds of nodes, so if they couldn't get it right the first time it might mean significant delays while they returned to ground and called someone. If you're going to go big on BiDi optics, establish a policy early on about which end uses the low-frequency transmit (TX) wavelength, which has better propagation characteristics. Intuition might suggest the more reliable band goes at the datacentre, but operationally you want remote devices to have the more reliable TX as this allows you to differentiate between a marginal fibre path and a power failure when something fails - which will inform if you're sending a guy out to flip a breaker, or if it's an OTDR job for a fibre specialist.
